UBM (Use Based Maintenance)

Use-based maintenance is a type of maintenance in which preventive maintenance actions are "guided" based on a specified use period. For instance, changing a car's gearbox oil after 12,500 miles. Because the action is guided by the use period, UBM would only be of use if there is a good overview of the condition over time. In this respect, the spread over useful life must be restricted. A further condition is observed in that condition over the course of time decreases, which means that the failure level tends to increase.
A UBM action is created in the same way as an FBM (Failure Based Maintenance) action (refer for identical fields). Three sections can be completed for a UBM action. These include the general data, Preventive and Costs, respectively. Optionally, there is also the Free field section. The general section and Costs section are completed in the same way as with the FBM action and will therefore not be described here.
The Preventive section is where the interval of the use-based maintenance action is defined. It consists of a time period and a time unit.

FIELD |
DESCRIPTION |
|
Description |
Users are free to enter any description for the object. The logical option is to describe the preventive action performed. |
|
Number |
A maintenance action can be numbered. When configured, the number will be listed in the tree with the description of the UBM. |
|
Maintenance time/unit |
Duration of the maintenance action. Select an appropriate unit of time. |
|
Mandatory |
This field can be set to indicate that the modeled maintenance is mandatory, for example
because of legislation. Marking it as mandatory is a signal that the maintenance should
not be changed or removed without careful consideration. This is highlighted by the
object icon |
|
Interval |
Frequency with which the use-based maintenance is carried out (choose also the time unit) |
|
Costs*) |
Costs can contain different sections: Maintenance category, Cost categories, and Total costs |
|
Maintenance category |
Select here from Minor maintenance, Major maintenance, and Renewal. |
|
Cost categories |
The options to enter in this field are predefined. Categories can be defined in the desktop version. Examples of cost categories include personnel, material, and equipment. |
|
Total costs |
This field has a dual function: If Cost Categories are not used, the user may enter a cost value directly in this field. If costs have been specified using the cost categories, then this field will automatically show the sum of these values; in this case the field will be read-only; only when all the values in the cost categories have been reset to 0, will the field Total costs become editable again. |
|
Environmental Impact |
Based on the categories configured in System Options, the impact categories appear. In the field, enter the category value to calculate the Total CO2e. To know about this option, see the topic Environmental Impact. |
|
Free fields*) |
If Free fields are enabled in the desktop version, each of the fields will be shown here and can be edited dependent on the user rights. |
|
*) |
These fields should be enabled in the desktop versions. See also: Other information. |
